[PATCH 1/5] Remove hypercall device

[PATCH 1/5] Remove hypercall device

[Anthony Liguori]

Removes hypercall device, old balloon device, and vmchannel stuff from QEMU.  The
stuff never was used publicly and is being/has been replaced by virtio.

Um.  This adds whitespace.  Reversed patch somehow?

Well, I think it is better to be explicit about it, but we do want to 
stay close to qemu, so I applied this.

The smaller the patch, the stronger the objections.

No, the whitespace is in QEMU SVN.  It somehow got removed from the 
kvm-userspace tree.

Well, perhaps send the reversed patch to qemu-devel as a bugfix?

Eh, removing a line of whitespace is not really a bugfix.  Maybe the 
double line was intentional by the author.  There are bigger fish to fry 
in terms of merging things into upstream QEMU, I don't really want to 
spend time fighting on whitespace issues :-)
